[Pablo64]

Only things around our place that hum are the alpacas, but it's a nice, pleasant kind of hum, so they can't be causing it.

About the alpacas . . .

humming when contented or when?

And, are some of them . . . ATYPICALLY as I consider the opposite to be generally true of the species . . .

are some of them affectionate?
